VANCOUVER, BRITISH COLUMBIA, December 7, 2017 - Millrock Resources Inc. (TSX-V: MRO, OTCQX: MLRKF) ("Millrock") is pleased to announce that sampling results for a comprehensive stream sediment sampling program and a targeted soil sampling program have been reported by partner Sojourn Exploration Inc., (TSX-V:SOJ) (“Sojourn”). The work program was recommended by Millrock as a logical follow-on step from the airborne geophysical survey and data compilation exercise that it had completed in 2016 – before Sojourn optioned the property. The geophysical surveys had identified a series of thirteen porphyry copper-gold targets, as well as five targets thought to represent possible volcanogenic sulfide mineralization.

The work was funded by Sojourn and indicates strongly anomalous metal concentrations in the immediate vicinity of several of the high-potential geophysical targets.

Phil St. George, Millrock’s Chief Exploration Officer, stated: “There is potential for both porphyry copper-gold deposits and volcanogenic massive sulfide deposits on this large land holding. Millrock and Sojourn have identified numerous high-priority drill targets through systematic, property-wide exploration; an approach that had been previously lacking. The targets are situated at the same stratigraphic level that has produced many other mines and deposits known to exist in the Golden Triangle District, and will be well worth drill testing.”

A total of 464 stream sediments and 324 soils were collected. Sojourn indicates in their press release the following summary of results:

Sojourn is earning a 100% interest in the Oweegee Dome property from Millrock by making share issuances totaling 2,300,000 common shares and completing $2,000,000 in exploration over the next three years.

Millrock holds a production royalty on the large claim block, which exceeds 300 square kilometers in area. It is located 75 kilometers northwest of Stewart, British Columbia, and is bisected by Highway 37 and the Northwest Transmission Line.

Quality Control – Quality AssuranceMillrock adheres to stringent Quality Assurance – Quality Control (QA/QC) standards. All samples were collected by Equity Engineering Consultants Ltd. (“Equity”) personnel under contract to Millrock and securely stored until delivery to the ALS Minerals prep lab in Terrace, British Columbia. After preparation the samples were sent for analysis at the ALS Minerals Ltd. North Vancouver, BC laboratory, a 17025:2005 certified facility. Equity implemented a QA/QC program utilizing duplicate sampling and blanks at an average rate of one duplicate or blank per 15 samples. No QA/QC anomalies were noted in the analyses. All results from blanks, standards and duplicates were reviewed and found to be accurate within acceptable tolerances for results obtained to date.
